AVR & Power Conditioning

AVR and power conditioning equipment corrects fluctuations in incoming grid voltage before they reach sensitive downstream equipment — protecting production lines, medical devices, telecom infrastructure, and test equipment from the voltage sags, surges, and instability of a real-world (or unreliable) supply. Unlike a grid simulator, which deliberately reproduces disturbance for testing purposes, an AVR or conditioner exists to remove it, holding output within a tight regulation band regardless of what the input does.

Preen's range covers both major approaches: the APH Series uses electromagnetic induction for cost-effective, high-overload regulation, while the APS Series uses fast solid-state compensation for the tightest regulation and quickest response.
